How Chargeable Weight Works
Carriers don't just charge by actual weight—they also consider package size. Chargeable weight (or billed weight) is the weight used to calculate your shipping cost.
If your package is heavy but compact, you pay for actual weight. If it's light but bulky, you pay for volumetric weight. Carriers compare both and charge the higher value.
Worked Example
Example: Shipping 2 different products
Product A (heavy item): 30cm × 20cm × 15cm, Actual: 8kg
- Volume = 30 × 20 × 15 = 9,000 cm³
- Volumetric weight = 9,000 ÷ 5000 = 1.8 kg
- Actual weight = 8 kg
- Chargeable = max(8, 1.8) = 8 kg (actual weight wins)
Product B (bulky item): 50cm × 40cm × 40cm, Actual: 5kg
- Volume = 50 × 40 × 40 = 80,000 cm³
- Volumetric weight = 80,000 ÷ 5000 = 16 kg
- Actual weight = 5 kg
- Chargeable = max(5, 16) = 16 kg (volumetric wins)
Total chargeable weight: 8 + 16 = 24 kg
With 0.5kg rounding: 8.0 + 16.0 = 24.0 kg (no change needed)
Tips to Reduce Chargeable Weight
- 1.Use right-sized packaging
Choose boxes that fit your product snugly. Excess space increases volumetric weight without protecting your item better.
- 2.Reduce void fill
Replace bulky packing peanuts with fitted foam inserts or air pillows that take less space.
- 3.Consider vacuum bags
For textiles and soft goods, vacuum sealing dramatically reduces package volume.
- 4.Ship flat-packed when possible
Furniture and assembly items can often ship in flat boxes, reducing volumetric weight by 50-70%.
Frequently Asked Questions
What is chargeable weight?
Chargeable weight (also called billed weight or billable weight) is the weight used by carriers to calculate your shipping cost. It's the greater of your actual weight or volumetric (dimensional) weight.
Why am I charged for volumetric weight?
Carriers charge volumetric weight when a package is large but light (like pillows or electronics boxes). This reflects the space your package occupies in their vehicles, which is valuable even if the package doesn't weigh much.
How do I reduce my chargeable weight?
To reduce chargeable weight: 1) Use smaller packaging that fits your product snugly, 2) Remove excess packing material, 3) Use vacuum bags for soft goods, 4) Consider flat-pack shipping for furniture.
Do all carriers round up chargeable weight?
Most carriers round up, but rules vary. DHL and FedEx typically round to the nearest 0.5kg. UPS may round to the nearest 0.1kg or whole kg depending on service. Always check your rate card for specific rules.
What's the difference between chargeable weight and dimensional weight?
Dimensional (volumetric) weight is calculated from package dimensions. Chargeable weight is the final billed weight—whichever is greater between actual and dimensional weight.
